Abstract
The invention discloses a rolling brush structure with an overload protection device. The rolling brush structure comprises a rolling brush body driven by a transmission motor to rotate, a connecting shaft arranged along the central axis of the rolling brush body and bristles spirally arranged on the rolling brush body, wherein a semicircular shaft is sleeved outside the connecting shaft; the overload protection device is arranged at the joint between the rolling brush body and a transmission belt and comprises two coated ratchet wheels arranged opposite to each and two embedded ratchet wheels arranged in the coated ratchet wheels; and a spring is connected between the two embedded ratchet wheels. According to the rolling brush structure with the overload protection device, as the overload protection device is arranged at the joint between the rolling brush body and the transmission belt, when the rolling brush body is obstructed and stuck, the two embedded ratchet wheels slip unidirectionally to the inner side to be separated from the two coated ratchet wheels, the coated ratchet wheels rotate normally under the condition of no load, accordingly, overheating of the motor, caused by influence from large resistance, is avoided, and fracture caused by frictional heating between the transmission belt and a motor driving shaft is prevented.
Description
Technical field
The invention belongs to the dust catcher field, particularly relate to the dust collector rolling brush structure that a kind of junction at round brush and driving belt is provided with overload protection arrangement.
Background technology
Dust catcher is a kind of sanitation and hygiene electrical equipment, is used for removing the dust in ground, carpet, wall, furniture, clothing and various slits.In general, dust catcher mainly comprises aspirator and suction line, be that the aspirator that dominant shape becomes is arranged in the dust catcher body with motor and blower fan, suction line comprises that suction nozzle, dust suction just managed and hose, and the air entry of the oriented under shed of suction nozzle also communicates with the air inlet of dust catcher body inner blower by the firm pipe of dust suction and hose.
In dust catcher when running,, the impeller of motor drives blower fan rotates at a high speed, and the air of dust catcher inside is discharged, and forms instantaneous vacuum in the inside of dust catcher, and forms a quite high Negative Pressure Difference between the ambient atmosphere.Under the effect of this Negative Pressure Difference, near the dust the suction nozzle sucks in the dust bucket in the dust catcher body by air entry together with air.The air that contains dust after filtering, is discharged to the dust catcher outside with the pure air after the dedusting again from the gas outlet in the dust bucket of dust catcher body.Like this, just reach the effect of dust out, cleaning floor.The suction rate of dust catcher is divided into a plurality of class of operating control, adapts to the scope of operation of different cleaning objects such as ground, bed surface, carpet, sofa, corner, in order to aspirate dust everywhere better.
According to dust collector structure and profile, be divided into vertical type dust collector, horizontal dust collector and portable dust collector etc. usually.Fig. 1 is the perspective view of prior art vertical type dust collector; Fig. 2 is the perspective view of looking up of prior art vertical type dust collector; Fig. 3 is the round brush mounting structure schematic diagram of prior art dust catcher; Fig. 4 is the structural representation of the dust collector rolling brush of prior art.As shown in Figures 1 to 4, vertical type dust collector comprises the handle of being convenient to user's push-and-pull 2 that is positioned at body 1 top, body 1 front portion is the protecgulum 4 with drain pan 3 combinations, the spare part of drain pan 3 sidewalls is inserted the standby rigidity sweep-up pipe 6 of pegging graft on the frame 5, and body 1 bottom is provided with the suction nozzle 9 that by suction nozzle loam cake 7 and suction nozzle chassis 8 suction through linking up with 33 be combined intos contains the foreign substances air along ground.The middle part at suction nozzle 9 rears is provided with a pair of coaxial front truckle 11, and also is provided with a pair of spacing of taking turns greater than the coaxial rear truckle 12 of front truckle 11 in the both sides, rear portion of drain pan 3 bottoms, and body moved forward and backward when these coaxial castors 11,12 were convenient to the dust suction operation.The left back position of drain pan 3 is provided with control pedal 13, and the effect of this control pedal is the body of control dust catcher and the angle of inclination of suction nozzle.
